Sunflecks in the upper canopy: dynamics of light‐use efficiency in sun and shade leaves of Fagus sylvatica

What is it about?

We found sun leaves to be more efficient at using sunflecks, both because of their faster photosynthetic induction and higher rates of CO2 assimilation under high light. This challenges the paradigm that sunflecks are primarily valuable for carbon uptake in the lower canopy and understorey and highlights their ubiquitous relevance for photosynthesis throughout the canopy.
